I think you're probably right, there should be a differential pressure (no
pun intended) between the outside of the case and the centerline of the
pinion. I'm not sure it would be enough, but it would probably be better
than a finned cover. I think I could integrate a cooler into the
cover--I'm looking at a diff cover as I type.

Hey Joe,
I've been stewing on that point for a long time and I think there is an
inherent pumping action. There is a passage cast into the case that I
think
catches the high velocity oil slung from the ring gear. I haven't looked
at
it in a long time but always kept it in the back of my mind as a potential
spot to tap off a small U tube cooler.

I am curious how one would connect a cooler to a diff (particularly one
on a
Spitfire). What troubles me is the fact that there is no inherent
pumping action that would force the oil through a cooler and back into the
diff. How is this done?
